GP Harmon handles a large volume of postconsumer papers generated from office buildings and sorted to remove other contamination. The quality and value of each grade depends on the degree of sorting involved.

Mixed Papers (MIX)
Mixed papers are clean, dry papers with trace levels of contamination such as plastics and other nonfiberous material. Papers are not separated by grade, and bales contain a variety of bleached, unbleached, groundwood and recycled papers.
